Those of us living in the good new days of tubes have no
trouble keeping them running with some good basic
technicianship and the appropriate tools.

constant current bias supplies

Don't make sense for tubes since their properties are a moving target.

or milling machines

to keep them going.

If you call what the typical tubed amp does, "going".
